Venting

So I really just need to vent. I lent money out to my dad and sister I mean no big deal they told me they were going to pay me back within a week. 3 weeks have gone by and no one has paid me back its nerve wracking when family does you wrong like this so I asked both of them today can they send me $10 so I can get something to eat for tomorrow mind you I'm 7weeks pregnant and they both have the nerve to tell me I need to manage my money better and they dont have any. Like what the actual hell so now I get to choose whether I want to do a quick shop at dollar tree or do I want to put it in my tank till Friday when I get paid. I mean really is it that hard to pay someone back when you owe them. & my hormones are all over so I may be overreacting
